Towage of the adherent

Wrong placement of baggage, and also can significantly worsen delivery of too heavy freights by car or the dragged adherent obedience and brake qualities of the vehicle / train that threateningly from formation of an extreme case on roads!

Prior to the movement always you check correctness of loading of the car and the adherent attentively.


The full mass of the adherent which accepts his own weight and mass of the established freight there should not pass an admissible maximum of the dragged adherent (watch specifications). The admissible maximum of the adherent depends on that, it is equipped with brake mechanisms, or not.

The maximum vertical load should not pass establishment of the car to prizepnoje with a full mass of the adherent of 75 kgs. For adherents with a full weight up to 500 kg it is necessary to hold it is necessary the following rule:

Vertical load of farkop has to form about 10% of the full mass of the adherent. For example, if the full mass of the adherent with freight of 225 kg equals, vertical load of prizepnoje has to form establishment along with these 22.5 kgs. Regulate load of car farkop, establishing freight on the adherent by the corresponding way. For the first recommended to establish freight in such a way that about 60% of its weight were before the adherent's axis, and 40% - behind. If the full weight of 500 kg of the adherent passes, try to distribute freight on the adherent's length more evenly (load of szepnoje optimum has to form institution 50 ÷ 75 KGS). You never load the adherent in such a way that thinking out the adherent outweighed a hall, leads to unloading of back wheels of the car that worsens connection of tires at tourist providing.

The full mass of the car and the dragged adherent should not pass the corresponding maximum admissible values (watch specifications).

The full mass of the car joins: snarjaschennuju the mass of the car, mass of the driver, passengers and baggage, mass of prizepnogo of the device and the adherent's measures falling on it. They remember that they the mass of the additional equipment defined on the car and the mass of the adherent which falls on farkop (at towage of the adherent) reduce payload capacity of transport by the corresponding sizes.


The surest way of check of correctness of loading of the car is and the adherent weighing. Nagruzte the car and the adherent thus as they are regulated in the train usually, and weigh them on freight scales.

Define values of full mass of the car and the adherent, and also masses which fall on an axis of cars and the adherent. Compare results of measurements to requirements of specifications.

prizepnoje establishment

The prizepnych device of devices which do not correspond after tiporasmeram massogabaritnym to characteristics of the adherent or is mistakenly certain on the car, can be the cause of damage of elements of a body of transport.


The design of prizepnogo of establishment which is intended for the device on the car has to meet all necessary requirements completely, - you advise yourself in service station of the enterprise Mercedes Benz.

prizepnoje establishment has to collect the strength of several specially provided points on the basis of a car body that loads of the dragged adherent were distributed more evenly and fell on elements of strengthening of a body. It is forbidden to install on the device prizepnyje car which lean only on the back buffer which is not intended for perception of similar loadings. Installation of farkopa has to be made by qualified personnel of car service.

They follow a condition of the spherical head of prizepnogo of the device. You keep the removable head together with a spare wheel in the luggage compartment of the car.

Violation of immunity of a course of the protection device at towage of the adherent can be at the expense of application of the prizepnogo stabilizer of the minimisiert device, - you address on original service stations Mercedes Benz.

If the adherent's weight with freight of 1500 kg passes, it is necessary to use the stabilizer surely.

Use of the stabilizer will not damage even if the adherent's weight with freight forms the smaller number of 1500 kg.

Rear-view mirrors

The device on the car of additional rear-view mirrors with the prolonged carriers demands towage of the large-caliber adherent usually. Report requirements of the local legislation and traffic regulations, the corresponding barges of adherents with cars. Connect the adherent in the car and estimate a step of deterioration in a rearview standard rear-view mirrors. If the review unsatisfactorily, so for the reasons of reliability it is necessary to equip special mirrors, guaranteeing to the driver the adequate review of the room behind car.

Joining of the adherent to the car

At acquisition of the adherent, equipped with brake mechanisms, you pursue that the last had an electric incentive of management, - the design of a hydraulic incentive of brake working system of the car does not provide a possibility of accession to its some additional contour, in particular, for commisioning of brake mechanisms of the adherent. Any option of accession to a brake hydraulic actuator of the car of the brake system of the adherent, it would not shine by which it is attractive, will lead to deterioration in efficiency of Bremsens of the car and immersion of reliability of the movement.

Including the adherent to the car, you always use a providing chain. The ends of a chain of providing have to be strengthened of course to appropriate places on dyschle of the adherent and on prizepnom establishment of the car. Pursue that the chain went under dyschlom of the adherent, ambushes of the forward end of dyschla on the road will prevent in case of rassojedinenija szepki. Free length of a chain has to be enough not to prevent execution of curves of the train with the minimum radiuses, nevertheless, the slow movement of a chain does not need to be allowed it is necessary to the country.

Devices of external lighting and Signalisierung on the adherent

Connection of the plug of the electric leading adherent's device to farkopu leads to automatic shutdown of the Parktronic system. Activization of system also automatically happens - you do not forget to be diminished also instationär the adapter 7/13 for joining of adherents with the contact plug 7.


For connection of the electric leading adherent's device, the adapter equipped with the contact plug 7 specially for instationär is used 7/13 (watch the prevention at the beginning of subsection).

1 — the Directing superiority
2 — the Directing flute


As on the adherent of various brands various transferring of the electric leading device can be used, it is necessary to charge the equipment farkopa of the expert of car service is necessary. In several cases can demand the adapter instationären device.

Before turning on the electric equipment of the adherent to the car power supply network, advise yourself in service station by all means.

Preparation for towage of the adherent

Prior to the movement it is necessary to make it is necessary control audit and check of the car and the adherent.

Measure vertical loading which falls on prizepnoje establishment, - you use usually napolnymi scales.

Check reliability of strengthening of dyschla of the adherent and a chain of providing.

Check technical condition of tires and pressure of air in the tire by car and the adherent. The reduced air pressure in the tire considerably worsens obedience of the car and train. By the way you control a state and pressure of air in a spare wheel.

It is completely loaded also the adherent in the car connected, you are convinced of absence is raised "prossedanija" constructing machines - as a last resort freight on the car / adherent.

Check serviceability of functioning of devices of external lighting and Signalisierung by car and the adherent.

Report the operating restrictions of PDD for the speed limit of the movement of the train in structure about the car and the adherent. Planning to make, a trip several countries, get acquainted with features of local requirements and restrictions in advance which concern towage of the adherent to cars as in each country of restriction can be considered.

In the European countries restriction of speed of the movement of the train is defined as a part of the car and the adherent at the height of 100 km for an hour.

Precautionary measures at towage of the adherent

It is necessary to consider it is necessary that the brake way of the car which drags the adherent increases. To itself therefore, with the adherent moving, it is necessary to support it is necessary for you the increased distance to the previous car. Try to avoid strong brakes and changes. It can lead to folding of the train or even the adherent's pereworatschiwaniju.

They remember that train length significantly passes length of the separate car. At change to the right you give between edge of a carriageway and to wheels of the right board of the car significantly of bolscheje removal as usual with to avoid a vyvozhdeniye on a position of wheels of the adherent on a border. Consider that at change of the train the adherent moves after a leaf of smaller radius, than the car, and or face on a barrier can go which freely escaped the car. At repair of other transport you do not hurry to come back in a row as it can lead to collision of the outdated car with the adherent.

The train is more sensitive, in comparison with the separate car, against action of blows of a side wind and aerodynamically wosmuschtschenijam from other cars. If you at great speed the heavy truck or the train overtakes, try to support just and uniform motion of the car. To reduce aerodynamically indignations, acting on the train from the previous car, reduce speed to leave current turbulentnogo.

At towage of the adherent load of all main devices and systems of the car increases. Therefore at frequent use of the car for towage of the adherent owe periodic maintenance of the car according to the office charter, it is characteristic of intense conditions of the enterprise (carry out watch chapter Routine maintenance).

Additional load of the car grows in working order trains in the hilly area even more. When overcoming long rises you follow the motor temperature mode after strelotschnomu to the list on the control panel attentively. At approach of an arrow of the list to an overheat zone, you exclude the air conditioner (if it is equipped and made) and you continue the movement. If temperature of the cooled liquid of the motor does not fall, or continues to increase, stop on a roadside and you allow the motor that it cooled down.

The conditioner of air needs to be excluded it is necessary also at rough increase in speed on descent at the movement in the hilly or mountainous territory. If temperature of the cooled motor liquid at the movement on the second transfer constantly increases, reduce the speed of the movement below than a note of 60 km for an hour.


At the movement in the hilly or mountainous territory cyclic switching of the third and fourth transfers of automatic transmission can be observed. In this case it is necessary to pass it is necessary in the reduced volume of "D3" that will prevent an overheat and excessive sale of details of elements of friction of AT. You use motor brakes for prevention of an overheat of brake mechanisms at the movement after long descents. For effective brakes of the motor will accept the reduced volume or one of the lowest steps of automatic transmission gears.

At a train break on rise you do not hold it on the place by means of Anpressens pedeli of gas, can lead to AT overheat. Use brake working system, or stojanotschnym from a brake.

At management of automatic transmission in the manual mode you use the third, second and first transfers, soobrasujas with a speed of the movement of the car and to tourist conditions. The adherent slowly, you do not accept the fourth transfer.

Saparkowywaja the train on a long stop, especially on descent or rise, you take all precautionary measures for sure brakes of the car and the adherent. Turn forward wheels of the car in such a way that they opposed at train skatywanii in bordjurnyj a stone. Completely you construct stojanotschnyj a brake and you transfer the Selektors lever of volumes to situation "R". On it is equipped RKPP models there will be the first, or accept the reverse gear. protiwootkatnyje which in addition lost you less than both wheels of the adherent boots.

Management of the train presents certain difficulties at Rückwärtsfahren and demands from the driver of special skills and a training. Move from a backing carefully and slowly, do not turn excessively quickly a steering wheel. When maneuvering a backing in the limited room are outside steady, at the same time someone it is useful, followed shifts of the adherent and directed your actions. Think that at turn of a steering wheel clockwise (to the right) the adherent moves on the left and vice versa. When maneuvering the train recommend to keep a backing in the steering wheel tire below (and not above as usual at the movement of a forward leg). At such chwate habitual compliance remains between the direction of change of a steering wheel and the movement of the adherent: removal of a hand leads to change of the adherent also on the left and vice versa on the left.
